Abstract
The leading corrections to electroweak precision observables in the MSSM with non-minimal flavor violation (NMFV) are calculated and the effects on MW and sin2 thetaeff are analyzed. The corrections are obtained by evaluating the full one-loop contributions from the third and second generation scalar quarks, including the mixing in the scalar top and charm, as well as in the scalar bottom and strange sector. Furthermore the leading corrections to the mass of the lightest MSSM Higgs boson, mh, is obtained. The electroweak one-loop contribution to MW can amount up to 140 MeV and up to 70x10-5 for sin2 thetaeff, allowing to set limits on the NMFV parameters. The corrections for mh are not significant for moderate generation mixing.
